Abstract (en)

[origin: US2009154709A1] Described is a technology by which computer data secrets sealed by a trusted platform module (TPM) or like device may be securely migrated from a physical source computing machine to a physically different destination machine. For example, migration of TPM secrets allows migration of a virtual machine from one physical machine to another. A destination machine receives a set of data sealed at a source machine. The set of data includes a migration key and a secret sealed by the migration key. The destination machine performs attestation with a key server to attest that the destination machine is entitled to access the sealed secret, via credentials, known good configuration and/or other policy compliance. The key server unseals the migration key, and provides a returned key (e.g., the migration key or a session key) to the destination machine for unsealing the secrets.
